It accepts a minimum bore diameter of 0.250 inches and reaches a maximum bore depth of 1.25 inches, making it well suited for shallow precision bores in a range of workpiece materials. The 3\/8 inch shank diameter provides rigid tool holding in standard boring bar holders. Overall length is 2.5 inches. At 0.12 pounds, the bar is lightweight enough for quick tool changes without sacrificing cutting stability. Machinists and toolroom operators working with steel, stainless, and hard alloys will find the M35 cobalt grade effective where standard high-speed steel loses edge retention.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use in manual and CNC lathe applications where small-diameter internal bores are required. Typical install scenarios include finishing bores in workholding fixtures, hydraulic components, bushings, and small mechanical housings. The right-hand cutting direction means the tool advances left toward the headstock in standard lathe orientation. It is a single-point tool suited for production and toolroom environments where consistent bore sizing is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM35 cobalt construction provides improved heat and wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.250 inches for small internal bore applications\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.25 inches suits shallow to mid-depth boring passes\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank diameter fits standard boring bar holders and quick-change toolposts\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for conventional lathe turning setups\u003c\/li\u003e\n\u003cli\u003eCompact 2.5 inch overall length minimizes overhang and chatter risk\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or addition for standard 3\/8 inch boring bar holders used in manual and CNC lathes requiring a right-hand single-point boring tool with a 0.250 inch minimum bore capacity.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before seating or adjusting the boring bar in the tool holder. Set tool height on center and ensure the shank is clamped with sufficient contact length to minimize deflection during cutting passes. Do not exceed the maximum bore depth rating in a single pass on hard materials.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 375-5020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689305014578,"sku":"375-5020","price":56.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19389360dc8340c7a63df0c3f05d55bf.jpg?v=1788257201","url":"https:\/\/voomisupply.com\/products\/value-collection-375-5020-boring-bar-m35-cobalt-3-8-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
